edges 2310fthe1. clip 10 are provided with the arcuate recesses 30whichsnfficiently expose, the end extensions 32, provided conventionallyon the razor blade 26' to permit said, blade'2,6, to be gripped betweenthe thumb and forefinger, thus facilitating adjustment of said blade mmthe slot 14* of'the,c lip 10. The cutting edge 22 of said blade '26.wil1, of course, be exposed in the spaces 20 between the teeth 18;. Thecut-away or relieved I corners 34 in the edg s 28: of the clip 10provide clearance for said clip 10 to, allow insertion of the clip intoany conventional double-edged safety razor. The edge 36 of the. clip'10; has a central arcuaterecess 38' while at each side of said arcuaterecess 38 and at equal distances from w it are the arcuate recesses 40,

" teeth to a position wherein the cutting edge abuts the Finally, it isan object to provide an attachment for inner surface 44, of they fold ofthe clip, 10. The inner surface 44 .of the fold acts, as a stop,preventing con; tinued movement of the blade 25 towards the edge 16oftheclip 10, thus eliminating the danger of complete exposureof thecutting edge 22 of said blade 26'. i In this connection, the opposingindexing shoulders 45-, pro vided on the sides of the guard adjacent tothe relieved corners 34, are functionally important in that the userlocates and aligns the razor blade'in the guard, prior to the insertionof the guard and blade in the razor holder;

using thumb and index finger to press the blade into position in theguard so that notch portions 47 of the razor blade register with thenotched portions 45 of the guard. In Fig. 3 of the drawing the blade 26is shown in a cutting position within the clip 10. The numeral 46denotes the clamp plate of a conventional type of double-edge safetyrazor. The clip 10 locates on the surface 48 of the clamp plate 4-6 sothat the edge of the clip at the arcuate recess 38 abuts against theboss 50 which is centrally positioned on the surface 48. Any tendency topivotal movement of the clip 10 about the boss 5*!) is prevented by theabutment of the edge 36 of said clip against the longitudinal boss 52 ofthe clamp plate 46. The clamp plate 54- is seated on the clip 19 so thatthe central hole 56 in said clamp plate 54 is in alignment with thearcuate recess 38 of the clip 10 and the boss 54 of the clamp plate 46.The arcuate recesses 40 in the clip 16 are provided to increase theversatility of the device, thus extending its use to those types ofsafety razors in which. the clamp plate 46 might support locating pinsof circular or square section, said pins being additional to boss 50 andreplacing boss 52. Insertion of the handle 58 in the hole 56 of theclamp plate 54 allows threadable engagement of said handle 58 with theinterior of the boss 59, with a consequent clamping action whicheffectively secures the clip 10 within the razor and the blade 26 withinsaid clip 10. Due to the flexibility of the material used for the clipand that of the conventional double-edged blade the blade is securelyheld in position and cannot shift after adjustment,

Referring to Fig. 4 in particular, the numeral 60 denotes a safety razorof a newer type, including the locating plate 62, which seats a razorblade for normal shaving purposes, the hinged clamp plates 64 pivotallymounted at the ends of the support bar 66, and the conventional openingmechanism actuated by the rotatable handle 68. The clip 10 containingthe blade 26 is placed on the locating plate 62 so that the edge of theclip at the arcuate recess 38 abuts against the boss 70. R0- tation ofthe handle 68 actuates the closing mechanism, causing the clamp plates64 to close towards the locating plate 62. It will be understood thatonly one of the hinge plates 62 will be actually effective in clampingthe clip 10 between said clamp plate and the locating plate 62, securelygripping the said clip 10 and simultaneously securely retaining therazor blade 26 within said clip 10 in any adjusted cutting position.

It will be seen by reference to Figs. 3 and 4 that the clip 10, whencontaining a razor blade and assembled within a razor, extendsconsiderably past the normal cutting station of the razor. This-featuregreatly facilitates the use of this invention in removing hair from overthe ears, under the arms and in clinical usepreparatory to surgicaloperations. The flexible character of the metal from which the inventionis fabricated proves advantageous in the application of the invention toirregular contour and surfaces and would also constitute an additionalsafety feature.

My clip may be used with the conventional double-edge razors and may belocated with the cutting edge 22 of the blade facing in either directionwith equal facility and security.

At all times the ends of the cutting edges of the blade will beconcealed and the user is thus protected. Furthermore, regardless of theparticular setting of the blade, my device provides a means which willcut hair very short, if desired, to a length in the order of thethickness of the metal used for the clip. In connection with my deviceblades otherwise discarded may be-used for certain hair cutting purposesaforementioned that could not be further used in ordinary shaving.

My device may also be used in trimming the ends of the hair for womenand girl with safety and will easily provide a desirable tapered outwhich allows the hair to lie smoothly. By maintaining the same generalangle of the razor handle the hair may be trimmed uniformly. The combedge 16 allows the clip to divide the hair equally and the hair isuniformly presented to the cutting edges with the result that the hairis not notched or cut with ragged edges.

The operation of this invention will be clearly comprehended from aconsideration of the foregoing description of the mechanical detailsthereof, taken in connection with the drawing and the above recitedobjects. It will be obvious that all said objects are amply achieved bythis invention.

Further description would appear to be unnecessary.

It is understood that minor variation from the form of the inventiondisclosed herein may be made without departure from the spirit and scopeof the invention, and that the specification and drawing are to beconsidered as merely illustrative rather than limiting.
